Patented July 18, 1933 UNITED STATES PATENT 10 mm CALVIN R. WEBBER, OFNEW YORK, N. Y., ASSIGNOR TO THE PACKEB MANUFACTURING (70., INC., 0]!NEW YORK, N. Y., A CORPORATION OF NEW YORK BOTTLE CLOSURE Applicationfiled April 25,

This invention relates to improvements in containers and closurescombined therewith.

It frequently occurs that in the distribution of certain liquids, aschemicals or medical specialties, it is desirable to carry, inconnection therewith, a relatively small amount of another liquidsubstance, which may or may not be required to mix with the contents ofthe main container.

Hitherto this has usually been accomplished by a separate, auxiliarycontainer, entirely independent of the first or main con tainer, andwhich requires extra expense and space in packing, besides otherdisadvantages, which are obvious to those familiar to the art to whichthis invention pertains.

It is therefore an object of the present invention to provide a. maincontainer, which may be an ordinary bottle provided with a relativelywide mouth, the bottle having a removable cap containing an axialinreachving member to which is attached an auxiliary receptacle, thesame to extend into the bottle neck.

A further feature is in the provision of means whereby the auxiliaryreceptacle may be readily attached or detached to the bottle cap, andwhen in an attached position to maintain its contents leak proof.Another aim is to provide a removable plug for the bottle cap throughwhich the contents may be distributed in such small quantities as isusually desirable.

These and other objects, such as the provision of an attractivecontainer, are accomplished by the novel design,rcon'struction, andcombination of parts hereinafter described and illustrated in theaccompanying drawing,

forming a material component of this disclosure, and in which The figureis a partial side clevational, partial vertical sectional view, takenthrough the upper portion of acontainel', as made in accordance with theinvention.

The main container, indicated generally by the numeral 5, is preferablymade of glass or like transparent material through which the contentsmay be seen, the shape of the container being circular, oval orrectangular, as referred. I

oined with the converging upper portion of the bottle 5 is aneck 6,preferably having an enlarged beadin 7, above which is a screw threadedend portion 8.-

A mam cap or closure element 9, is prefer- -1930. Serial No. 447,175.

ably made of. phenol condensate rosins, or other firm substance notreadily aflected by ordinary chemicals, water, oils or changes intemperature, this closure including an outer skirt portion 10, which maybe fancifully formed and corrugated to provide an elliclent gri Extening inwardly, concentric with the exterior of the cap, is an axialprojection 11 provided on its outer surface with coarse screw threads12, tapering from its innermost end to the upper, solid portion of thecap. v

An inner auxiliary receptacle 14 is generally cylindrical and providedwith closed lower end, the receptacle being preferably made ofcellulose, chemically prepared and treated in a manner to render ittransparent and at the same time capable of yielding so as to besubstantially unbreakable.

The upper end of the inner receptacle 14. is molded or formed to presentscrew threads 15, adapted to snugly fit the conical threads 12 of thecap, its extreme ?upper end being.

flared outwardly to present a flange 16 suited to contact with theinverted base of the cap element 11. i

Set in the upper end of the annular recess, formed between the closureelements 10 and 11, is a flexible washer 17 against which the outwardlyflared end 16 of. the inner receptacle makes contact, while on theunderside of the flange element 16, resting tightly against the upperedge of the bottle neck, is a similar washer 18.

From the foregoing it will be seen that a substantially impervious jointmay be formed, so that the contents of the inner receptacle 14, such asoil or other liquids, is maintained at all times in a safe and effectivemanner.

main container, an axial opening 20 is formed through the element 11,and provided with a plug 21, having a sharply conical point {at itsinner end and screw t reads 22 on its 24 by which the plug may bescrewed firnily shank to engage corresponding threads in the upperportion of the cap.

Above the screw threads is a cylindrical body 23, provided with apolygonal sided cap against a washer 25, set concentrically in the upperside of the cap.

Obviously upon removing this plug, the contents of the main containermay be shaken out in such small quantities as may be desired.

As changes of construction could be made within the scope of theinvention, it is in tended that all matter contained in the foregoingdescription or shown in the accompanying drawing shall be interpreted asillustrative and not in a limiting sense.

Having tlius described'the invention, what is claimed as new and desiredto be secured by Leters Patent. is

1. The combination with a container hav-' ing a hollow circular neck anda screw thread on. its upper portion, of a cap engageable thereon, aplug integral with said cap to ex- '2. The combination with a containerhaving an externally threaded mouth, of a cap fitted to engage thethreads, a pair of packing washers interposed between said cap and thecontainer top, a concentric plug on said cap having a tapered thread, anauxiliary receptacle having threaded engagement with said plug andextending into the container, and a flange on said auxiliary receptacleextending between said washers.

3. The combination with a rigid container having a threaded mouth, of arigid cap having a skirt portion engaged on said mouth, a threadedconical plug on said cap spaced from the skirt portion, a yieldingcylindrical receptacle having one end closed and the other engaging saidconical threaded plug, an outstanding flange at the extremity of saidreceptacle. and means for gripping said flange to form an imperviousjoint.

4. A combination with a container having an'externally threaded mouth ofa cap fitted toengage the threads, a concentric plug on said cap havingatapered thread, an auxiliary receptacle having a threaded engagementwith said plug and extending into the container. and a pair of packingwashers, one of which is interposed between the cap and the open upperedge of the receptacle and the other of which surrounds and closelyengages the receptacle and is interposed between the upper washer andthe container mouth, the wedging effect of the taper on the central plugserving to assist the washers in the tight sealing of the opening intothe receptacle and the opening into the container.

5. A combination with a container having 'an externally threaded mouthof a cap fitly engages the receptacle and is interposed between theupper washer and the container mouth, the wedging effect of theta per onthe central plug serving to assist the washers in the tight sealing ofthe opening into the receptacle and the opening into the container, thesaid taper on the plug also serving to force the wall of the receptacleoutwardly and increase the sealing effect of the second mentioned Washerbetween the receptacle and the container mouth.

6. A container having a screw cap, a receptacle formed'of yieldingmaterial and having a flared mouth providing a flange extending over themouth of the container, said receptacle being removably engaged to saidcap to suspend the receptacle in the .container, said cap having anaxial sprinkler passage communicating with said receptacle, a plugcontrolling the mentioned passage, the said receptacle being normallysecured to said cap and removable from the container therewith wherebythe cap and receptacle form a unitary closure for the container, andmeans associated with said flange for sealing the container.

7. A container having a screw cap, a plug on said cap extendinginto thecontainer, a receptacle formed of yielding material and having a flaredmouth providing' a flange extending overthe mouth of the container,

said receptacle being removably engaged to with the flared end of saidreceptacle for sealing the end of said container.
